Function Documentation

SCIP_RETCODE SCIPincludeObjPresol	(	SCIP *	scip,
		scip::ObjPresol *	objpresol,
		SCIP_Bool	deleteobject
	)

creates the presolver for the given presolver object and includes it in SCIP

The method should be called in one of the following ways:

1. The user is resposible of deleting the object: SCIP_CALL( SCIPcreate(&scip) ); ... MyPresol* mypresol = new MyPresol(...); SCIP_CALL( SCIPincludeObjPresol(scip, &mypresol, FALSE) ); ... SCIP_CALL( SCIPfree(&scip) ); delete mypresol; // delete presol AFTER SCIPfree() !

1. The object pointer is passed to SCIP and deleted by SCIP in the SCIPfree() call: SCIP_CALL( SCIPcreate(&scip) ); ... SCIP_CALL( SCIPincludeObjPresol(scip, new MyPresol(...), TRUE) ); ... SCIP_CALL( SCIPfree(&scip) ); // destructor of MyPresol is called here

creates the presolver for the given presolver object and includes it in SCIP

Parameters

scip	SCIP data structure
objpresol	presolver object
deleteobject	should the presolver object be deleted when presolver is freed?
